    Areas affected...Deep South Texas

    Concerning...Severe Thunderstorm Watch 198...

    Valid 110550Z - 110715Z

    The severe weather threat for Severe Thunderstorm Watch 198
    continues.

    SUMMARY...Isolated strong to marginally severe wind gusts will
    remain possible in Deep South Texas. Given weakening trends observed
    over the last hour, a downstream watch is not anticipated.

    DISCUSSION...Both lightning and radar trends have shown a general
    decrease in intensity of convection moving into Deep South Texas.
    Recent observed wind gusts with a surging portion of the convective
    line from George West/Beeville have been 32-38 kt. As this line
    continues southward, MLCIN will remain relatively low given the
    mid/upper 70s F dewpoints. Occasionally strong/marginally severe
    gusts could occur in an isolated sense. Larger buoyancy resides near
    the Rio Grande. Stronger cells within the valley could also produce
    damaging gusts and perhaps large hail. Given the observed trends, a
    downstream watch is not anticipated.
